i recently started to build my first own quadcopter, but sadly nothing seems to work. I'm trying to use an Arduino together with my smartphone as a remote controller. When I power up my drone almost nothing happens.Even if I connect my drone with usb to the pc and start the MultiWii Gui nothing happens.
Because I couldn't manage to change the baudrate of my bluetooth transmitter I even tried to change it in the arduino sketch to 9600. But this didn't help me neither.
The parts I'm using:
Arduino UNO Rev. 3
ESC: DYS SN20A Mini 20A SimonK
http://www.banggood.com/DYS-SN20A-Mini- ... ds=myorder
Motors: Racerstar Racing Edition 2205 BR2205 2300KV
http://www.banggood.com/4X-Racerstar-22 ... ds=myorder
10DOF: GY-87 10DOF MPU6050 HMC5883L BMP180
http://www.banggood.com/GY-87-10DOF-MPU ... ds=myorder
Transmitter: HC-05 Wireless Bluetooth Serial Transceive
http://www.banggood.com/HC-05-Wireless- ... ds=myorder
I connected everything like this:
ESC's
ESC 1 to Arduino Pin 3
ESC 2 to Arduino Pin 9
ESC 3 to Arduino Pin 10
ESC 4 to Arduino Pin 11
GY-87
VCC to 5V
GND to GND
SDA to Arduino Pin A4
SCL to Arduino Pin A5
INT to Arduino Pin 2
HC-05
VCC to 3.3V
GND to GND
TX to Arduino Pin 5
RX to Arduino Pin 6
I changed everything in the sketch according to the Multiwii Wiki.
My changes
Code: Select all
#define QUADX
Code: Select all
#define MINTHROTTLE 1064 // special ESC (simonk)
Code: Select all
#define INTERNAL_I2C_PULLUPS
Code: Select all
#define MPU6050 //combo + ACC
Code: Select all
#define HMC5883
Do I have to make some more changes to the sketch?
I would be unbelievable happy If someone could help me with my build.
Best regards
Artas
